Description

  The present invention relates to a temporary train line drawing device that temporarily pulls a train line in place of a support device in order to finely adjust a support position of the train line in a train line support device that supports the train line.

Conventionally, there is a train line support device including a movable bracket described in Patent Document 1. The movable bracket of the train line support device includes a horizontal main pipe 3, an inclined pipe 4, and a bracing pipe 5 for hanging and supporting the train line on the utility pole P. The main pipe 3 is fixed to the utility pole P on the base end side with the attachment band B, and extends in the horizontal direction via the insulator G. The inclined pipe 4 is also fixed to the utility pole P on the base end side with a mounting band B, extends obliquely upward through the insulator G, is coupled to the distal end portion of the main pipe 3, and cooperates with the main pipe 3 to Form. The bracing pipe 5 is installed between the main pipe 3 and the inclined pipe 4 and extends horizontally below the main pipe 3. The upper part of the arm support device 1 is fixed to the anti-vibration pipe 5 and the lower part of the arm support device 1 supports the arm 7 of the curving device 6.

Japanese Utility Model Publication No. 5-82644

As the speed of trains increases, the slight height or deviation of each trolley wire support device forms a hard point on the trolley wire, leading to local wear. For this reason, it is necessary to finely adjust the vertical position and the horizontal position of the part holding the trolley line and the suspension line.
The only way to adjust the support position of the arm 7 up and down is to change the positions of the upper and lower two attachment bands B. However, it is substantially impossible to finely adjust the positions of the upper and lower two attachment bands B in a state where the trolley line and the suspension line are supported.
In particular, if the support position is adjusted in a state where force is applied to the trolley wire or the suspension line in a direction away from the utility pole, it is difficult to adjust and fix the position of the support device while pulling the trolley wire or the suspension line toward the utility pole side. It is. In addition, the movable bracket must be fixed in consideration of bending due to the load when the train line is fixed. Confirmation is a heavy work burden.
Therefore, the invention according to this application provides a temporary train wire pulling device for supporting position adjustment work for temporarily holding the trolley wire or the suspension line when adjusting the support position of the trolley wire or the suspension line. Is an issue.

In order to solve the above-mentioned problems, in the invention according to this application, the supporting devices 1 and 9 are supported by the support structure and extend in the left-right direction perpendicular to the front-rear direction which is the extending direction of the train lines T, M. In order to temporarily hold the train lines T and M instead of the support device during the operation of adjusting the support position of the train lines T and M on the movable bracket 2 that supports the train lines T and M via the The wire temporary drawing devices 40 and 50 are used. The train wire temporary pulling devices 40 and 50 are attached to the mounting members 41 and 51 which can be mounted on the pipes 3 and 5 extending horizontally in the left-right direction of the movable bracket 2 and the train lines T and M are pulled to the proximal end side of the movable bracket 2. A pair of pulleys 47 and 57 provided before and after the support devices 1 and 9 so as to be freely extended in the extending direction and supporting these pulleys 47 and 57, and the train lines T and Length adjusting members 45 and 55 that can be changed in length are connected to the mounting members 41 and 51 so that M is arranged.
On the way from the mounting members 41, 51 to the pulley 47, a detour member 46 having a bent portion deviating from the extending direction of the length adjusting member 45 is interposed so as to avoid interference with the movable bracket 2 or its accessory.
The mounting member 41 protrudes from the movable bracket 2 in the vertical direction and receives a pulling load on the train lines T and M via the length adjusting members 45 and 55 and the pulleys 47 and 57 at a required position. Posts 43 and 53 to which 45 and 55 are connected were fixed.
The length adjusting member is composed of turnbuckles 45 and 55.

  According to the train line temporary pulling device of the invention according to this application, when the train line is supported on the movable bracket via the support device, the train line is temporarily held instead of the support device. It is possible to make fine adjustments freely while releasing the tension of the line, greatly reducing the burden of adjustment work, and supporting the train line at an appropriate position reduces local wear at the hard point of the trolley line. Can be prevented. The support position of the temporarily supported train line can be arranged by following the support device to be finely adjusted by changing the mounting position of the mounting member or the length of the length adjusting member. Furthermore, since it can be attached without interfering with surrounding members such as a movable bracket, a wide installation position can be secured.
